Construction Method of Belgian Road in Test Track

Abstract

The invention discloses a method for constructing a Belgian road in a testing track. Pavements with different sunk characteristics are distributed on the Belgian road. The construction method comprises the following steps: (1) laying a cement steady stone chip layer; (2) carrying out coordinate stake-out by using a full-station electronic distance measuring instrument; (3) measuring sinusoidal altitudes of the highest and lowest points of the pavement on a steel chisel pile by using a precise level, marking on the steel chisel, drawing a white construction line among the steel chisels on each side of the pavement as a reference line according to the mark; (4) mounting Belgian stone blocks; (5) checking the altitude of the Belgian stone blocks; and (6) pouring cracks, namely pouring cracks after mortar reaches certain strength, cleaning and moistening the cracks before treatment, and pouring mortar more than or equal to 52.5# cement into the cracks. Compared with the prior art, the method has the advantages that the construction efficiency is greatly improved and labor and material costs are well saved.

Description

technical field [0001] The invention relates to the field of road surface construction, in particular to a construction method for a Belgian road in a test track. Background technique [0002] The Belgian road is derived from the stone road in Belgium. It is a typical concave and convex bad road. It is named as a representative of a typical bad road. It is a road test for the reliability and durability of the vehicle quality. The length of the Belgian road of a typical proving ground is not less than 500 meters. The conventional construction method is to directly pave stones on the original terrain, and rely on manual determination of elevation with a ruler. The construction progress of this construction method is slow, and repeated measurements are required to determine the elevation. Because the initial setting time of cement mortar is short, it often fails or degrades before the elevation is measured, which affects the quality and progress of the project. Contents of t...
