Product Introduction

Asphalt mixture pavement structure depth meterDetailed information:

Asphalt mixture pavement structure depth meterAlso known as manual sanding machine (electric sanding machine), the anti-skid performance of road surface refers to the force generated by the sliding of vehicle tires along the surface when they are subjected to braking. Usually, anti-skid performance is regarded as a surface characteristic of the road surface and expressed by the friction coefficient between the tire and the road surface. Surface characteristics include fine and coarse structures on the road surface, and factors that affect skid resistance include road surface characteristics, road moisture level, and driving speed.

The sand paving instrument is suitable for measuring the macroscopic roughness of road surfaces. This method is applicable for determining the depth of surface structure of asphalt and cement concrete roads, and is used to evaluate the macroscopic roughness, drainage performance, and anti-skid performance of road surfaces. The on-site CBR tester is designed and manufactured according to JTJ059-95 "Code for On site Testing of Highway Roadbeds and Pavements", and is suitable for measuring the on-site GBR values of various soil based materials on highways.

Main technical parameters:

1. Measuring cylinder, with a volume of 25 ± 0.15 millimeters
2. Spread the board. Stick a 2-4mm rubber sheet below
3. Windshield board
4. Construct depth gauge
