低剂量水泥改性级配碎石基层路面Low dosage cement modified graded crushed stone base pavement

技术领域technical field

本发明涉及路面结构，尤其涉及低剂量水泥改性级配碎石基层路面。The invention relates to a pavement structure, in particular to a low-dose cement modified graded crushed stone base pavement.

背景技术Background technique

我国公路交通飞速发展，为了适应重载交通日益增长的需要，道路界对水泥、石灰等无机结合料稳定碎石形成的半刚性基层路面结构开展了大量的研究。半刚性基层具有良好的板体性、较大的刚度、较高的扩散荷载能力以及承载能力，使得其上的沥青面层最大弯拉应力值降低，从而提高了沥青面层抵抗行车疲劳破坏的能力。因此，半刚性基层被广泛应用在高等级公路的路面基层中，国内已建成的高速公路中90%以上是半刚性基层路面。然而半刚性基层自身固有的易于收缩开裂、自愈能力差的缺陷，导致路面开裂严重；路面结构排水条件差，雨水聚积后，在高速行车下容易产生唧泥，从而导致沥青面层网裂破坏。With the rapid development of my country's highway traffic, in order to meet the increasing needs of heavy-duty traffic, the road industry has carried out a lot of research on the semi-rigid base pavement structure formed by cement, lime and other inorganic binders stabilized by gravel. The semi-rigid base has good plate properties, high rigidity, high diffusion load capacity and bearing capacity, which reduces the maximum bending and tensile stress value of the asphalt pavement on it, thereby improving the asphalt pavement's ability to resist driving fatigue damage. ability. Therefore, semi-rigid base is widely used in the pavement base of high-grade highways, and more than 90% of the domestic expressways are semi-rigid base pavements. However, the inherent defects of the semi-rigid base layer, which is easy to shrink and crack, and has poor self-healing ability, lead to serious pavement cracking; the pavement structure has poor drainage conditions, and after rainwater accumulates, it is easy to generate mud under high-speed driving, which leads to network cracking and damage to the asphalt surface layer. .

在沥青面层与半刚性基层之间设置级配碎石之类松散型的柔性材料，是一种有效地延缓沥青路面反射开裂的方法。采用优质级配碎石作为半刚性路面结构过渡层，能起消减应力的作用，有效地防止半刚性路面反射裂缝病害的出现，从而延缓或消除沥青路面的其它病害。Setting loose flexible materials such as graded crushed stone between the asphalt pavement and the semi-rigid base is an effective method to delay the reflective cracking of asphalt pavement. The use of high-quality graded crushed stone as the transition layer of the semi-rigid pavement structure can reduce stress and effectively prevent the occurrence of reflective cracks on the semi-rigid pavement, thereby delaying or eliminating other diseases of the asphalt pavement.

级配碎石基层处于半刚性基层的上面，对于半刚性基层是很好的隔温保护层。它保护未开裂的半刚性基层避免产生温度收缩裂缝，也可隔断半刚性基层的已有裂缝对沥青面层的影响，甚至消除反射裂缝。同时，由于骨料之间的嵌锁作用，使级配碎石成为能够承受一定交通荷载的结构层。The graded crushed stone base is on top of the semi-rigid base, which is a good thermal insulation layer for the semi-rigid base. It protects the uncracked semi-rigid base from thermal shrinkage cracks, and can also block the impact of existing cracks in the semi-rigid base on the asphalt surface, and even eliminate reflective cracks. At the same time, due to the interlocking effect between the aggregates, the graded crushed stone becomes a structural layer that can bear certain traffic loads.

但由于级配碎石是一种松散材料，一般具有塑性变形大、刚度小、应力扩散能力差、耐冲刷性能差等缺点，同时实际工程中（特别对于二级及其以下公路），级配碎石的料源差，破碎加工、堆放、拌和、运输、摊铺、找平等一系列生产施工环节质量难以严格控制，易导致材料结构级配不合理，成型后的混合料均匀性差，其应用效果并不能总是得到保证，在重交通作用下会产生过大的工后变形，致使沥青路面平整度受到影响，严重时会使沥青面层产生剪切和疲劳破坏。同时，抗冲刷能力低，更加剧了沥青路面的破坏。为了解决这些问题，同时继续保持级配碎石阻止或延缓半刚性基层沥青路面反射裂缝的作用，有必要研究提出一种新型的路面结构。However, since graded crushed stone is a kind of loose material, it generally has the disadvantages of large plastic deformation, low stiffness, poor stress diffusion ability, and poor erosion resistance. The source of gravel is poor, and it is difficult to strictly control the quality of a series of production and construction links such as crushing, processing, stacking, mixing, transportation, paving, and leveling, which will easily lead to unreasonable material structure grading and poor uniformity of the mixed material after molding. The effect cannot always be guaranteed. Excessive post-construction deformation will occur under the action of heavy traffic, which will affect the smoothness of the asphalt pavement. In severe cases, it will cause shear and fatigue damage to the asphalt surface. At the same time, the low erosion resistance further aggravates the damage of the asphalt pavement. In order to solve these problems while maintaining the role of graded gravel in preventing or delaying reflective cracks in semi-rigid base asphalt pavement, it is necessary to study and propose a new pavement structure.

所述低剂量水泥改性级配碎石基层中铺设有土工构件。Geotechnical components are laid in the low-dose cement modified graded crushed stone base.

所述土工构件为土工格栅或土工格网或土工格室。The geotechnical components are geogrids, geogrids or geocells.

所述防渗粘结层与土基之间设有半刚性材料基层。A base layer of semi-rigid material is provided between the anti-seepage bonding layer and the soil foundation.

所述低剂量水泥改性级配碎石基层为加入1%～2.5%质量百分比水泥作为粘接料的低剂量水泥改性级配碎石基层。The low-dose cement modified graded crushed stone base is a low-dose cement modified graded crushed stone base added with 1% to 2.5% by mass of cement as a binder.

所述低剂量水泥改性级配碎石基层中级配碎石组成范围满足：0.075mm筛孔对应质量通过率0～7%，0.6mm筛孔对应质量通过率6%～25%，2.36mm筛孔对应质量通过率16%～40%，4.75mm筛孔对应质量通过率22%～55%，9.50mm筛孔对应质量通过率31%～80%，19.0mm筛孔对应质量通过率60%～95%，26.5mm筛孔对应质量通过率79%～100%，31.5mm筛孔对应质量通过率100%；液限<28%，塑指<9%，压碎值<26%。The composition range of the graded crushed stone in the low-dose cement modified graded crushed stone base meets: 0.075mm sieve hole corresponds to a mass pass rate of 0-7%, 0.6mm sieve hole corresponds to a mass pass rate of 6%-25%, and a 2.36mm sieve hole corresponds to a mass pass rate of 6%-25%. The quality passing rate of the hole is 16%~40%, the quality passing rate of 4.75mm sieve hole is 22%~55%, the quality passing rate of 9.50mm sieve hole is 31%~80%, and the quality passing rate of 19.0mm sieve hole is 60%~ 95%, the 26.5mm sieve hole corresponds to a quality pass rate of 79% to 100%, and the 31.5mm sieve hole corresponds to a quality pass rate of 100%; the liquid limit is <28%, the plastic index is <9%, and the crush value is <26%.

与现有技术相比，本发明的优点在于：Compared with the prior art, the present invention has the advantages of:

本发明在沥青混凝土面层与防渗粘结层之间铺设低剂量水泥改性级配碎石基层，通过低剂量的水泥对级配碎石的强度、水稳定性和耐久性等加以改善，试验和理论研究以及工程实践证明，在满足结构强度要求的前提下，这种改性级配碎石材料能够有效地减少半刚性材料的收缩开裂、提高级配碎石水稳定性能、发挥级配碎石的排水性能，在改善现有级配碎石体积稳定性、力学性能、长期性能以及施工性方面存在诸多优势。本发明低剂量水泥改性级配碎石基层中加入的作为粘接料的水泥剂量为1%～2.5%质量百分比，这与常规水泥稳定碎石的研究出发点不同，加入的水泥剂量大小有明显区别，本发明在级配碎石中加入1%～2.5%质量百分比水泥后获得的改性级配碎石仍属于松散类的材料，而不是类水泥稳定碎石的板体性材料；本发明的低剂量水泥改性级配碎石基层既提高了稳定性能，又能满足碎石基层材料路用性能要求，保持级配碎石阻止或延缓半刚性基层沥青路面反射裂缝的作用、排水作用的同时，克服了级配碎石作为松散材料的缺陷，避免使用级配碎石基层的沥青路面出现早期破坏现象。以1%～2.5%质量百分比水泥作为粘接料，可改善较差质量的级配碎石的物理力学特性、路用性能和耐久性，从而可放宽级配碎石组成范围要求，适应实际工程中级配碎石质量难以保证的现实，增强级配碎石技术经济优势，以便推广应用。本发明可进一步在低剂量水泥改性级配碎石基层中铺设有土工构件，加强级配碎石材料结构的整体性，提高其刚度、承载能力和抗变形能力。防渗粘结层可以预防路面内部水下渗侵入低剂量水泥改性级配碎石基层下部，增强路基路面结构抗水损害能力。In the present invention, a low-dose cement-modified graded macadam base is laid between the asphalt concrete surface layer and the anti-seepage bonding layer, and the strength, water stability and durability of the graded macadam are improved by the low-dose cement, Experiments, theoretical studies, and engineering practice have proved that on the premise of meeting the structural strength requirements, this modified graded crushed stone material can effectively reduce the shrinkage and cracking of semi-rigid materials, improve the water stability of graded crushed stones, and play a role in grading. The drainage performance of crushed stone has many advantages in improving the volume stability, mechanical properties, long-term performance and constructability of existing graded crushed stone. The amount of cement added as a binder in the low-dose cement modified graded crushed stone base of the present invention is 1% to 2.5% by mass, which is different from the research starting point of conventional cement-stabilized crushed stone, and the amount of added cement has obvious differences. The difference is that the modified graded crushed stone obtained after adding 1% to 2.5% by mass of cement to the graded crushed stone in the present invention is still a loose material, rather than a board-like material of cement-stabilized crushed stone; the present invention The low-dose cement modified graded macadam base not only improves the stability performance, but also meets the pavement performance requirements of the macadam base material, and maintains the effect of graded macadam in preventing or delaying the reflective cracks and drainage of semi-rigid base asphalt pavement. At the same time, it overcomes the defect of graded crushed stone as a loose material, and avoids early failure of the asphalt pavement using graded crushed stone base. Using 1% to 2.5% by mass cement as a binder can improve the physical and mechanical properties, road performance and durability of poor-quality graded crushed stones, thereby relaxing the composition range requirements of graded crushed stones and adapting to actual engineering In view of the fact that the quality of medium-graded crushed stone is difficult to guarantee, the technical and economic advantages of graded crushed stone should be enhanced for popularization and application. In the present invention, geotechnical components can be further laid in the low-dose cement-modified graded crushed stone base to strengthen the integrity of the graded crushed stone material structure and improve its rigidity, bearing capacity and deformation resistance. The anti-seepage bonding layer can prevent the internal water seepage of the pavement from intruding into the lower part of the low-dose cement modified graded crushed stone base, and enhance the water damage resistance of the subgrade and pavement structure.

Improve the strength, water stability and durability of graded crushed stone with low dosage of cement. Experiments, theoretical research and engineering practice have proved that this modified graded crushed stone can meet the requirements of structural strength. Stone materials can effectively reduce the shrinkage and cracking of semi-rigid materials, improve the water stability of graded crushed stones, and exert the drainage performance of graded crushed stones. There are many advantages to sex.

本实施例在低剂量水泥改性级配碎石基层2中铺设有土工构件3，可加强级配碎石材料结构的整体性，提高其刚度、承载能力和抗变形能力。土工构件3为土工格栅或土工格网或土工格室，防渗粘结层4为防渗土工布层或防水粘油层，防渗粘结层4可以预防路面内部水下渗侵入低剂量水泥改性级配碎石基层2下部，增强路基路面结构抗水损害能力。本实施例选用土工格栅作为土工构件3，选用防渗土工布层作为防渗粘结层4。In this embodiment, ageotechnical component 3 is laid in the low-dose cement-modified graded crushedstone base 2, which can strengthen the structural integrity of the graded crushed stone material and improve its rigidity, bearing capacity and deformation resistance. Thegeotechnical component 3 is a geogrid or geogrid or geocell, and the anti-seepageadhesive layer 4 is an anti-seepage geotextile layer or a waterproof sticky oil layer, and the anti-seepageadhesive layer 4 can prevent the water seepage inside the road from invading low-dose cement The lower part of the modified graded crushedstone base 2 enhances the water damage resistance of the subgrade and pavement structure. In this embodiment, a geogrid is selected as thegeotechnical component 3 , and an anti-seepage geotextile layer is selected as theanti-seepage bonding layer 4 .

本实施例中，低剂量水泥改性级配碎石基层2中加入1%～2.5%质量百分比水泥作为粘接料，这与常规水泥稳定碎石的研究出发点不同，加入的水泥剂量大小有明显区别，本发明在级配碎石中加入1%～2.5%质量百分比水泥后获得的改性级配碎石仍属于松散类的材料，而不是类水泥稳定碎石的板体性材料；本发明中低剂量水泥改性级配碎石基层2既提高了稳定性能，又能满足碎石基层材料路用性能要求，其继续保持级配碎石阻止或延缓半刚性基层沥青路面反射裂缝的作用、排水作用的同时，克服了级配碎石作为松散材料的缺陷，避免使用级配碎石基层的沥青路面出现早期破坏现象。In this example, 1% to 2.5% by mass cement is added to the low-dose cement-modified graded crushedstone base 2 as a binder. The difference is that the modified graded crushed stone obtained after adding 1% to 2.5% by mass of cement to the graded crushed stone in the present invention is still a loose material, rather than a board-like material of cement-stabilized crushed stone; the present invention Medium and low dose cement modified graded crushedstone base 2 not only improves the stability performance, but also meets the road performance requirements of crushed stone base materials, and it continues to maintain the function of graded crushed stones to prevent or delay the reflective cracking of semi-rigid base asphalt pavement, At the same time, it overcomes the defect of graded gravel as a loose material and avoids early failure of asphalt pavement using graded gravel base.

低剂量水泥改性级配碎石基层2中级配碎石组成范围满足：0.075mm筛孔对应质量通过率0～7%，0.6mm筛孔对应质量通过率6%～25%，2.36mm筛孔对应质量通过率16%～40%，4.75mm筛孔对应质量通过率22%～55%，9.50mm筛孔对应质量通过率31%～80%，19.0mm筛孔对应质量通过率60%～95%，26.5mm筛孔对应质量通过率79%～100%，31.5mm筛孔对应质量通过率100%；液限<28%，塑指<9%，压碎值<26%。由于以1%～2.5%质量百分比水泥作为粘接料，可改善较差质量的级配碎石的物理力学特性、路用性能和耐久性，从而可放宽级配碎石组成范围要求，适应实际工程中级配碎石质量难以保证的现实，增强级配碎石技术经济优势，以便推广应用。Low-dose cement modified graded crushedstone base 2 The composition range of graded crushed stone meets: 0.075mm sieve hole corresponds to a mass pass rate of 0-7%, 0.6mm sieve hole corresponds to a mass pass rate of 6%-25%, 2.36mm sieve hole The corresponding quality passing rate is 16%~40%, the corresponding quality passing rate of 4.75mm sieve hole is 22%~55%, the corresponding quality passing rate of 9.50mm sieve hole is 31%~80%, and the corresponding quality passing rate of 19.0mm sieve hole is 60%~95% %, the 26.5mm sieve hole corresponds to a mass pass rate of 79% to 100%, and the 31.5mm sieve hole corresponds to a mass pass rate of 100%; the liquid limit is <28%, the plastic index is <9%, and the crush value is <26%. Since 1% to 2.5% by mass cement is used as a binder, the physical and mechanical properties, road performance and durability of poor-quality graded crushed stones can be improved, so that the requirements for the composition range of graded crushed stones can be relaxed and adapted to the actual situation. In view of the fact that the quality of graded crushed stone is difficult to guarantee in engineering, the technical and economic advantages of graded crushed stone are enhanced for popularization and application.

本实施例中，0.075mm筛孔对应质量通过率0%，0.6mm筛孔对应质量通过率8%，2.36mm筛孔对应质量通过率18.8%，4.75mm筛孔对应质量通过率29%，9.50mm筛孔对应质量通过率44.4%，19.0mm筛孔对应质量通过率68%，26.5mm筛孔对应质量通过率87.6%，31.5mm筛孔对应质量通过率100%；液限18.2%，塑限16.3%，塑指为1.9%，压碎值24.3%。In this embodiment, the 0.075mm sieve hole corresponds to a mass pass rate of 0%, the 0.6mm sieve hole corresponds to a mass pass rate of 8%, the 2.36mm sieve hole corresponds to a mass pass rate of 18.8%, the 4.75mm sieve hole corresponds to a mass pass rate of 29%, and the 9.50 mm sieve hole corresponds to a mass pass rate of 44.4%, a 19.0mm sieve hole corresponds to a quality pass rate of 68%, a 26.5mm sieve hole corresponds to a quality pass rate of 87.6%, and a 31.5mm sieve hole corresponds to a mass pass rate of 100%; the liquid limit is 18.2%, and the plastic limit 16.3%, the plastic finger is 1.9%, and the crush value is 24.3%.

图2示出了本发明的第二种低剂量水泥改性级配碎石基层路面实施例，本实施例与上一实施例基本相同，区别仅在于：防渗粘结层4与土基6之间设有半刚性材料基层5。Fig. 2 shows the second embodiment of low-dosage cement modified graded crushed stone base pavement of the present invention, this embodiment is basically the same as the previous embodiment, the only difference is:anti-seepage bonding layer 4 and soil base 6 Abase layer 5 of semi-rigid material is provided between them.
