The present application relates to a kind of rural road pavement widening construction methods in rainy area, including the following steps, the material component, density and
moisture content of widening section
subgrade should be same with the material component, density and
moisture content of old roadbed same level layer, the side middle part of old road
cement concrete layer is drilled and planted with reinforcement with interval distance, adjacent planted reinforcement interval is 40-50cm, then a layer of SBS anti-
cracking paste is uniformly arranged along joint;1-1.5cm thick rubber stress absorbing layer is spread on the upper end surface of new and old road
cement concrete layer;With new
asphalt, regenerating agent material, graded RAP material, aggregate and mineral
powder are mixed in hot state, then
asphalt concrete
surface layer is paved on the upper end of rubber stress absorbing layer, and the thickness is 5-8cm.The present application prevents
water damage caused by rain, delays damage at joint, reduces the probability of crack occurrence, and improves the service performance and durability of pavement.
