Title: Innovations by Laurence M Sylvester
Introduction
Laurence M Sylvester is an accomplished inventor based in Tiburon, CA (US). He holds a total of 3 patents that showcase his expertise in the field of rubber modified asphalt cement. His innovative approaches have contributed significantly to paving and roofing applications.
Latest Patents
One of his latest patents is titled "Quick-setting cationic aqueous emulsions using pre-treated rubber modified asphalt cement." This invention involves creating cationic aqueous emulsions of rubber modified asphalt cement (RMAC) that can be used for various applications, including paving and roofing. The process begins with combining 45 to 90% by weight asphalt with 5% to 55% by weight solid recycled rubber, such as crumb rubber from used vehicle tires. The RMAC is then treated with dodecyl benzenesulfonic acid (DDBSA) to lower its viscosity before emulsifying it in an aqueous medium.
Another significant patent is "Rubber modified asphalt cement compositions and methods." This invention outlines methods for producing improved RMAC compositions that are useful in paving, roofing, and sealing applications. The method involves combining asphalt with RVPR and at least one dodecyl or tridecylbenzene sulfonic acid in the presence of moderate heat. The resultant RMAC mixtures exhibit enhanced properties, such as increased softening point and improved recovery from deformation.
