Embodiment 1

[0037] Embodiment 1: a kind of polymer SRX asphalt road construction technology, with reference to the attached figure 1 , the polymer SRX asphalt road construction process here is suitable for the construction of semi-rigid base asphalt pavement.

[0038] Step A:

[0039] Preparations required before construction.

[0040] Specifically, the underlayment of the road is made into a trough section. For the road section made of trough section, excavate drainage ditches alternately at intervals of 5-10m on the shoulders on both sides. The underlying layer meets the road arch, flatness and compaction specified in the construction. Complete the re-measurement of the guide points and benchmarking points on both sides of the road required for construction.

[0041] Step B:

[0042] Bottom cleaning and treatment.

[0043] Specifically, before filling the foundation of the foundation filling section, the earth shall be bulldozed first, and then the earthwork excavated at the botto...

Abstract

The invention discloses a polymer SRX asphalt road construction process, which is characterized by comprising the steps of A, performing preparation required before construction; B, performing bottom layer clearing and treatment; C, performing base layer measurement and sample lofting; D, performing piling and wire hanging; E, stirring mixed materials; F, transporting polymer SRX stable macadam mixtures; G, spreading the polymer SRX stable macadam mixtures; H, performing roller compaction on the polymer SRX stable macadam mixtures; I, caring the polymer stable macadam base layer. By using the technical scheme, the road composite structure made of the polymer SRX stable macadam mixtures has the characteristics of high intensity and high toughness; the road cracking condition is avoided; the service life of the road is prolonged; the effect of the full-thick type asphalt pavement can be achieved only by using half of the manufacturing cost of the conventional asphalt concrete of the polymer SRX stable macadam mixtures; the economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a polymer SRX asphalt road construction process. Background technique [0002] With the leap-forward development of my country's economy and society, the people's requirements for infrastructure construction are also getting higher and higher. In order to match the economic foundation, the country has also invested a lot of money in infrastructure construction. Among them, highways are the main means of transportation, especially for areas with relatively backward economy, the construction of highways is even more significant. However, with the popularization and coverage of the road network, the asphalt roads in the past can no longer meet the current production needs. The roads paved with traditional asphalt concrete construction, due to the characteristics of asphalt itself, coupled with the influence of different aspects encountered in the construction process As a...
