Must be taken to dry, mixed with lime and other technical measures. Road-packing maximum size should be less than 100mm, road-top camber slope and cross slope should be consistent.
Drying must be taken, mixed with lime and other technical measures. Road bed packing maximum particle size should be less than 100mm, the top surface of the road bed transverse slope gradient should be consistent with the way the arch.
We must take the technical measures such as drying, lime. Roadbed filler should be less than the maximum diameter 100mm, roadbed top cross slope should be consistent with the crown slope.
