In 1926 James King, the first asphalt salesman in New Jersey, along with Joseph Dosch, formed the Dosch-King Company, Inc. They entered the liquid tar and asphalt distribution field, and over the years have grown to operating in New Jersey, New York, Connecticut, Pennsylvania, and Rhode Island. At the peak of the liquid business they sold over six million gallons per year. When Joseph Dosch died, James King III bought out the Dosch interests and became the sole owner of the corporation.

In 1970, Dosch King Emulsions was formed and has been a successful road emulsion manufacturing plant ever since. Recently they began introducing polymer additives to various grades of products, providing a much greater stone retention on chip seal work.

Dosch King does complete road construction, rough grading, fine grading, storm drains, curbs, sidewalks, and full-depth paving. In New Jersey, Pennsylvania and Connecticut, Dosch King specializes in Chip Seal work, using the most modern computerized liquid distributor trucks and computerized chip spreaders. These units permit exact application of liquid and stone chips, effecting uniform, excellent results.

In 2001, the Dosch King Company became involved in the preventative maintenance process of Microsurfacing. Dosch King believes this process will greatly compliment its already existing products.

After 75 years of successful business, the company is now in the fourth King generation.
