Description

Bituminous mixture compactness detector

Technical Field

The utility model relates to a pitch compactness detects technical field, specifically is a bituminous mixture compactness detector.

Background

The compaction requirement of the asphalt road is as follows:

1 laboratory Standard Density 96% or 98%

2% of the maximum theoretical density of 92% or 94%

3 98% or 99% of the density of the test section

4 in detail, see the current industry standard JTG F40-2004 technical Specification for construction of asphalt road surfaces for roads.

The detection methods for the compaction degree of the asphalt pavement include the following methods:

firstly, a circular cutting method is a destructive detection method and is suitable for fine soil without aggregate. The advantages are that the equipment is simple and convenient to operate; the disadvantages are that the soil quality limits are applied, when the cutting ring is driven into the soil, the generated stress loosens the soil, and the stress generated when the wall thickness is larger, so the dry density is reduced.

The sand filling method is a destructive detection method and is suitable for various soils. The method has the advantages that the measured value is accurate; the disadvantage is that the operation is complicated, and the density and cone weight of the standard sand must be measured frequently.

And the nuclear density instrument method is one non-destructive measurement method. The device can rapidly measure the wet density and the water content, meets the requirements of rapidness and no damage on site, has the advantages of convenient operation and visual display, and can be used after being compared and calibrated with a sand filling method.

The nuclear densitometer method is a non-destructive measuring method, and has the advantages of high detection effect, convenient operation, unique detection data, no comparison of multiple groups of data and low reliability of the detected data.

There is therefore a need for an asphalt compaction tester that ameliorates the above problems.
