Abstract
The invention discloses a construction method applied to temporary road foundation soil solidification and polymer concrete overlay, and belongs to the technical field of road construction. The construction method comprises a polymer concrete surface layer, a second solidified soil layer and a first solidified soil layer. The construction method comprises the following steps: 1, constructing a solidified soil base layer and a subbase layer; 2, detecting the subbase layer; 3, conducting construction lofting; 4, paving plain soil; 5, spraying a curing agent; 6, mixing the mixture; 7, conducting initial pressing of solidified soil; 8, conducting final pressing leveling and maintenance; and 9, preparing the novel multi-dimensional polymer concrete overlay. The method is suitable for various roads, terrace base layers and roadbeds; and the solidified soil layers have enough strength and stability, have certain water invasion resistance in southern areas, have small shrinkage deformation and strong erosion resistance, and have the comprehensive advantages of reliable quality, overall cost reduction, shorter construction period and more environmental protection.
Description
technical field [0001] The invention relates to the technical field of road construction, and more specifically relates to a construction method applied to temporary road foundation soil solidification and aggregate concrete overlay.
