The strength and therability of three types of material,including penetrated asphalt mixture,penetrated cement concrete and penetrated brick, are analyzed in technical aspect.

The application of concrete in perpetual pavement;

Stress of asphalt overlay laying on cracked concrete pavement repaired with bridging slab;

Test research of anti-vibration performance of riving on the structure of concrete pavementsp;

On the endurance of cement concrete;

Analysis on the quality control of rural cement concrete roadway construction;

Vibration analysis on coarse aggregate gradation of interlocking-dense cement concrete;

High performance polymer surfactants in cement and concrete;

Lignosulfonates containing different cations were prepared with calcium lignosulfonate as raw material by way of ion exchange to study systematically their effects on properties of cement and concrete and related mechanism.

In order to explore and study acting mechanism of steel slag in cement and concrete,Ca 2+ Ion dissolving out characteristics of five steel slag pwders coming from different region were studied with a self-designed and made instrument.

Study on proportion of porous concrete mixture;

Prediction of the performance of porous concrete using ANFIS;

On the basis of studying factors that affects porous concrete strength,prepared surface materials with compressive strength more than 30?MPa and meet requirements of permeability modulus more than 1?mm/s.
