PHASE II REPORT - Caltrans

5.4.3.2 Construction
The following construction guidelines must be followed:
• The treatment mix design can be placed only after the contractor has satisfactorily
demonstrated proper placement procedures on non-test section locations.
• All transverse construction joints must be placed outside the test sections (e.g.,
within the transitions between test sections).
The distance between the transition areas must be sufficient to allow changes in materials
during construction. The distance is required to accommodate changes in material type in a
manner that will reduce the influence on the properties of the finished pavement. Each test
section will have a minimum of 100 feet (30.5 m) before and after the monitored length to
provide sufficient production to develop consistency after changes in materials.
The mixture for the treatment will be documented using the forms in Appendix G, which include
the type and quantities (rates) for each of the following:
• Polymer-modified emulsified asphalt cement
• Well-graded crushed mineral aggregate
• Mineral filler (normally portland cement or lime)
• Water
• Other mixing aid additives (normally emulsifying agents)
The project team shall provide the mix design information to the contractor and agency prior to
the beginning of the project.
The equipment used for the application of the treatment shall also be documented using the
forms in Appendix G, which will contain the following information:
• Type of paving equipment (continuous, truck-mounted)
• Type of spreader box
The breaking and curing rates of the treatment will be collected and entered on the Equipment
Form provided in Appendix G.
