AI Technical Summary
Technical Problem
In the renovation of old concrete roads, the poor drainage capacity at the intersection of sidewalks and roads leads to serious water accumulation problems, affecting the quality of the roads.
Method used
The road base is treated with crushed stone, and drainage geogrids and waterproof geotextiles are overlapped to form a rapid drainage structure. The water is separated by an emulsified asphalt layer and a drainage pipe system, and rapid drainage is achieved by combining a filter layer and a grid plate.
Benefits of technology
It improves the drainage capacity of the road structure, reduces water disturbance problems, and reduces quality risks such as settlement and reflective cracks caused by water disturbance. The construction is simple and cost-effective.

Abstract
This invention provides a construction method for improving the drainage capacity of road structures, relating to the field of drainage function technology for the renovation and upgrading of old roads. It separates water bodies between the upper and lower structural layers and the original ground surfaces on both sides of the road structure layer by forming an emulsified asphalt layer and waterproof geotextile. A rapid drainage structure is formed using a concrete pavement crushed stone layer, filled with crushed stone, drainage geogrids, sidewalk rubble, a filter layer, and drainage pipes. This achieves rapid drainage of the road structure, ensuring the stability of the road structure layer in the renovation of old pavements, reducing differential settlement caused by groundwater and other factors, and avoiding disturbance to the road and the resulting reflective cracks. This invention improves the drainage performance at the junction of sidewalks and roads, reducing water disturbance problems.
