Semi-rigid base material and construction process
The invention discloses a semi-rigid base material and a construction process. Wherein the semi-rigid base material comprises the following components in parts by weight: 100 parts of aggregate, 3.0-5.0 parts of an anti-cracking silicon-aluminum-based cementing material and 4.0-6.5 parts of water, the aggregate is pebbles, the surfaces of the pebbles are clean, a large amount of chippings, needle-sheet-shaped particles and the like are not generated, the strength of the pavement can be remarkably improved, and the semi-rigid base material is an environment-friendly material. Meanwhile, the semi-rigid base material obtained by compounding the pebbles and the anti-cracking silicon-aluminum-based cementing material is slightly influenced by changes of environment temperature and humidity, the phenomenon of dry shrinkage of the pavement can be remarkably improved, cracks are reduced, and the strength and durability of the pavement are improved. According to the construction process of the semi-rigid base material, cracks can be reduced, the construction period can be shortened, and remarkable economic benefits are achieved.
本发明公开了一种半刚性基层材料及施工工艺。其中半刚性基层材料按重量份计包括集料100份，抗裂性硅铝基胶凝材料3.0～5.0份，水4.0～6.5份，集料为卵石，卵石表面干净，不会产生大量碎屑、针片状颗粒等，可以显著提高路面的强度，是一种环境友好型材料。同时通过将卵石与抗裂性硅铝基胶凝材料复配得到的半刚性基层材料受环境温度、湿度变化的影响较小，能够显著改善路面干缩的现象，减少裂缝的产生，提高路面的强度和耐久性。本发明提供的半刚性基层材料的施工工艺能够减少裂缝生成，缩短施工周期，具有显著的经济效益。
