Temporary road pavement technology

Abstract

The invention discloses a temporary road pavement technology which comprises the following steps: I. paving a cushion, namely selecting rubbles with grain size of 150mm below according to the needed amount, paving the rubbles onto a selected and compacted road surface to form a rubber layer; crushing the rubble layer through a press until rubbles in the rubble layer cannot be loosened; II. paving a surface layer, namely selecting fine rubbles with the particle size of 5-10mm according to the needed amount; blending the fine rubbles with dry soil, spraying water while blending until dry soil is formed into clay which is adhered to fine rubbles to form a clay-bound rubble layer; paving the clay-bound rubble layer on the cushion, leveling, milling through the press until the surface of the clay-bound rubble layer has no obvious wheel trace; and III. paving a wear layer. The temporary road pavement technology has the beneficial effects of good road flatness, difficulty offlying of dust and sand, and incapability of enabling the road surface to be muddy in rainy days.

Description

Technical field [0001] The invention relates to the technical field of road construction, in particular to a temporary road paving process. Background technique [0002] Due to the particularity of the photovoltaic field, its service life is subject to certain restrictions. In order to save costs, the roads in the field basically use temporary roads. [0003] The construction method of the aforementioned temporary roads is generally to compact the soil of the selected road section first, and then lay gravel on the compacted soil. For temporary roads paved in this way, the bonding strength between the gravel layer and the 3 soil layers is not strong, and the smoothness of the road is poor. The sand particles in the soil layer and the gravel layer below are easy to play under the action of wind. Dust; on rainy days, under the action of external forces (such as pedestrians), the lower soil layer becomes mud, which is easy to cause the road surface to be muddy and slippery, or due to ...

AI Technical Summary

Problems solved by technology

For the temporary road paved in this way, the bonding strength between the crushed stone layer and the soil layer is not strong, and the smoothness of the road is poor. Dust; on rainy days, under the action of external forces (such as pedestrians), the lower soil layer turns into mud, which can easily lead to muddy and slippery road surfaces, or the gravel is exposed on the road surface due to the loss of the soil layer and slips, which is a safety hazard for pedestrians. Great inconvenience for safe walking

[0004] In addition, due to the insufficient water saturation in the soil layer of the existing temporary road and the insufficient bonding strength between the soil layer and the gravel layer, the temporary road is prone to deformation due to the loss of the soil layer after being washed by rainwater, thus improving the road safety. Repair times, increasing repair and maintenance costs
