Technical Field

The invention provides a method for improving the overall skid resistance of a roadway, and belongs to the fields of traffic, municipal engineering and the like.

Background

The method for separating the road surface is a multi-lane road surface passing method, and for the road surface on which a plurality of motor vehicles can run in the same direction, traffic marked lines are adopted for separation, and the traffic marked lines play a role in inducing and separating driving, such as common white solid lines, white dotted lines and the like on the road. However, the anti-skid performance of the traffic marking cannot reach the same level of the asphalt concrete pavement, and particularly in a rainy area, under the condition of a wet pavement, when a vehicle changes lanes, the traffic marking is pressed, and the vehicle is easy to sideslip, so that the vehicle and an adjacent vehicle are scratched, and even more serious consequences are caused because the vehicle sideslip is out of control. The overall skid resistance of the roadway is reduced due to the traffic marking, and a place worthy of improvement is provided.

Disclosure of Invention

[ problem ] to

The technical problem to be solved by the invention is as follows: the anti-skid performance of the traffic marking can not reach the same level of the asphalt concrete pavement, so that the overall anti-skid performance of the roadway is low.

[ solution ]

The invention provides a method for improving the overall skid resistance of a roadway, which comprises the following steps:

the method comprises the following steps: determining the lane separation position according to the traffic safety facility engineering construction drawing, and making a positioning mark by using fly ash;

step two: milling and planing the road surface with the positioning mark with milling and planing equipment to form a strip-shaped groove;

step three: cleaning and dedusting the groove, and pouring adhesive layer asphalt;

step four: backfilling the groove with colored asphalt concrete, wherein the virtual pavement thickness after backfilling is larger than the actual depth of the groove;

step five: rolling and compacting; the compacted colored asphalt concrete pavement is required to be smooth with the surrounding pavement;

step six: and (4) detecting the skid resistance strength and the flatness index of the pavement, and opening the traffic after the indexes are met.

In one embodiment of the invention, the groove has a width of 15-25cm and a depth of 1 cm.

In one embodiment of the invention, the dummy layer is slightly deeper than the trench by 1.1-1.2 cm.

In one embodiment of the invention, the colored asphalt concrete adopts modified colored asphalt binder, the coloring agent adopts special pigment for colored asphalt concrete, the performance index meets the requirement of GB/T32984, and the mineral material performance index meets the requirement of technical Specification for road asphalt pavement construction JTGF 40.

In one embodiment of the invention, the color of the special color asphalt concrete pigment is yellow or green or red or other colors different from black.

In one embodiment of the invention, the pavement is an asphalt concrete pavement.

The invention also provides an anti-skid road surface which is characterized by consisting of a traffic marking with anti-skid performance and a driving road surface, wherein the traffic marking with anti-skid performance is made of colored asphalt concrete, the driving road surface is an asphalt concrete road surface, grooves are arranged on the driving road surface, and the traffic marking with anti-skid performance is positioned in the grooves.

In one embodiment of the invention, the traffic markings are lane separation lines, zebra stripes.

[ advantageous effects ]

The novel pavement plane separation method plays a role in inducing and separating driving, can replace traffic markings, and improves the overall skid resistance of the roadway, thereby improving the driving stability and safety of vehicles.

The colored asphalt concrete (yellow, green, red and the like) is used for replacing traffic markings to separate the road surfaces, so that the overall skid resistance of the asphalt road surfaces can be improved, the identification of drivers on the plane separation of the road surfaces is facilitated, the black asphalt road surfaces are separated by colored asphalt strips, the overall view of the road can be improved, the fatigue feeling of the drivers is relieved, and the driving comfort level is improved.
