Introduction

 

Active silicon is a kind of siliceous sedimentary rock by biogenic. It’s composed of Non-crystal structure: SiO2,Al2O3,CaO,MgO,K2O,Na2O,P2O5 and other organic materials 

 

The Chemical compostion of Active Silicon as the Bitumen Modifier 

Item	PH	SiO2	Al2O3	Fe2O3	Na2O	MgO	K2O	CaO	TiO2	Ignition Loss
Active Silicon	6.5-7.5	85.00%	6.39%	2.71%	0.51%	0.64%	1.14%	0.43%	0.45%	6.33%

Characteristics 

1. Containing large number of SiO2, so it has many nanometer micro holes both inside and outside.

2. Porous, Acid-resistant, Soda-resistant. Wide specific surface area, Stable chemical property, Thermo stabilization and High adorability.

3. Easily attached to aggregate surface after being added into asphalt to decrease the fluidity of the bitumen, and then increase the modulus of elasticity.

4. As the Active silicon can improve the physical performance of the asphalt mixtures, it can decrease the penetration of bitumen in mixtures while increasing the soften point, residual stability and dynamic stability.

Functions:

1. Improving the adhesive ability and adhesive strength of asphalt in mixtures, then increasing the hardness of bitumen to change the high temperature performance of mixtures, then make the asphalt mixture high density, low permeability and decrease the growth rate of hardening in later period.

2. Improving the anti-aging, anti-strain of the road.

3. Substantially improving the anti-skidding, abrasive resistance and the chemical stability of the road

4. Improving the anti-corrosion, acid-resistance and soda-resistance of the road

5. The cyclic annular structure of active silicon can prevent the refraction of sunshine on the road, improve the safety of driving

6. As the active silicon can increase the density of the mixture materials, decrease the voidage, it can improve the shock absorption of the road.

7. Not affected by temperature, oxidation, sunshine, ultraviolet ray and other external conditions

Operating method:

Add the active silicon directly into the aggregate with normal asphalt directly then weld into mixture materials.
