4th & Miller

4th & Miller

As part of the City of Coeur d’Alene’s efforts to beautify the Midtown area, the Streets Department undertook to replace the intersection at 4th and Miller. A total of 58 cubic yards of concrete were placed on two separate pours. The existing intersection was one of several in the midtown area composed of colored concrete pavers needing replacement after wear from traffic and several harsh winters. A state of the art integral color system allowed us to determine the exact blend of color pigments and dosage per cubic yard based on data provided by the facility that supplied the last pavers . A concrete mix design was customized to match the slump (consistency), rock and sand proportions, cement and water content – all of which are factors that affect the final color. Maintaining workability and moisture in the surface for proper curing was particularly challenging in the warm conditions as the water content had to remain consistent with prior pours and throughout this pour in order to maintain uniformity of the color and general durability. This required the use of water reducing admixtures. Minimizing water through this method also enabled us to create a mix with exceptionally high early strength. This particular mix achieved its designed 28 day strength of 4000 PSI in just 3 days, allowing the City of CDA to put traffic on it promptly, minimizing congestion and inconvenience to travelers and local business owners. CDA Redi Mix & Precast, Inc. is proud to be a part of the city’s efforts to maintain beautiful and durable roads.
