Yes we do! We'd be happy to meet with you to discuss your options and to help you make a decision as to which may be the best for your property.
This concept of reinforcing asphalts with a carbon black filler has been made practical by pelletizing the carbon black with a high-durability maltenes binder compatible with asphalts. The pellets are packaged in 11.34-kg (25 lb) polyethylene bags which are introduced, bag and all, into hot-mix cycle of asphalt concrete batch-type plants.
Evaluation of Pyrolized Carbon Black from Scrap Tires as in Hot Mix Asphalt INTRODUCTION Pyrolized carbon black (CBp) is a by-product of waste tires. Pyrolysis is a method of decomposing waste tires by a cooking process in order to break down the tire into salable by-products.

The researchers will study the physical and chemical properties of the steel smudge with the latest methods. They will also examine in detail what different additions will own cementitious qualities. Furthermore, they will design different new types of cement and concrete, and test it.
Although asphalt is widely used and accepted as the go-to material for constructing our road systems, scientists are always looking for ways to improve the thermal and mechanical characteristics of it. One major downfall of asphalt is the amount of heat it absorbs during daylight hours due to its low solar reflectance value (0.04-0.06).
The contact state between layers of asphalt pavement not only has a significant effect on the mechanical response of road structure but is also the bottleneck of research on the mechanical behavior of pavement structure at present. In this paper, the effects and laws of different water–salt entry modes, salt solution concentrations, and temperatures coupling on the contact state between base ...
Carbon black has been used as a modifier in conventional binders together with a relatively low percentage of SBS polymer. In addition, an Evotherm additive has been combined by the wet way with the aim of decreasing the manufacturing temperature of the asphalt mixtures.
USING PYROLIZED CARBON BLACK (PCB) FROM WASTE TIRES IN ASPHALT PAVEMENTS (PART I: LIMESTONE AGGREGATE). FINAL REPORT. This study presents the viability of using pyrolized carbon black (PCB) as an additive in hot mix asphalt concrete.

Although this particle size is too large to enable the recycled carbon black to be reincorporated into new tires, it can be used effectively as a filler for asphalt concrete mixtures. One tire will yield approximately 7-8 pounds of carbon black.
CARBON BLACK AS A REINFORCING AGENT FOR ASPHALT. This paper is intended to familiarize asphalt technologists with the unique properties of carbon black and its use as a reinforcing agent for asphalt cements. This effect is obtained with properly selected grades of carbon black.
