Paving

Standards
All paving and associated materials (i.e., asphalt concrete (AC) pavement, base course, portland concrete cement (PCC), etc.) placed within the City of Temecula shall conform to the:
  • All applicable ordinances, standard notes, policies and procedures including water quality practices
  • Chapter 18 of the Temecula Municipal Code
  • City and engineering standards
  • City’s Engineering and Construction Manual
  • Standard Specifications for Public Works Construction (GreenBook) latest edition
Paving Notes
The Department of Public Works shall oversee all paving performed within the City limits. The City’s current Paving Notes (PDF) are intended to be used on all plans for private development and public right-of-way improvements subject to, but not limited to:
  • Precise grading/paving improvements
    • Driveways
    • Private/public parking lots
    • Private/public streets
  • Storm drain improvements
  • Street improvements
  • Trench repairs
Permits
All associated permits for paving operations shall be obtained prior to performing any paving. A grading permit may be required if paving on private development; an encroachment permit shall be required if paving within public right-of-way.

Mix Designs
All paving mix designs shall be submitted for review and approval by the City Engineer.

Asphalt Concrete Materials
  • AC materials shall conform to section 203-6 of the GreenBook and current City standards.
    • Type C2 PG70-10 for finish and overlay courses. This course shall be a minimum of 0.12 foot (1½ inches) thick including grind and overlay installations.
    • Type B PG70-10 for base course. This course shall contain the balance of the required AC thickness. The minimum AC lift for base course is 0.21 foot (2½ inches).
  • The minimum AC thickness is 0.33 foot (4 inches).
  • The maximum AC lift is 0.33 foot (4 inches).
“Shoving” is a type of AC pavement failure that may be caused by asphalt mixes that are too rich in asphalt, that have course/fine aggregate that is too rounded, etc. Typically, shoving results at hills, curves or intersections, caused by braking or accelerating vehicular forces. To prevent or minimize shoving, the City reserves the right to require a modified AC mix design with properties that provide high stability (i.e., ability to resist shoving and rutting, angular aggregate particles with a rough surface texture, etc.) in compliance with the GreenBook and/or Caltrans specifications.

Base Course Materials
  • Base materials shall conform to provisions of the GreenBook and current City standards.
  • For street sections, base course material shall be Crushed Aggregate Base (CAB) or Crushed Miscellaneous Base (CMB) per section 200-2 of the GreenBook. Principal and Urban Arterial roads require CAB.
Portland Concrete Cement (PCC)
All PCC used shall conform to provisions of the GreenBook and current City standards.

Trench Repairs
  • When trenching streets, all trenches shall conform to City and engineering standards. Refer to City Standard No. 407 “Trench/Pothole Repair” for trench maintenance and/or repairs.
  • If trenches in close proximity and parallel to gutter lines result in leaving pavement strips in distress or less than 2 feet in width (between the trench and gutter line), said pavement strips shall be removed and repaved, at the discretion of the City Engineer.
  •  A tack coat shall be applied to join existing asphalt concrete and vertical surfaces in compliance with the GreenBook.
Inspections
All paving shall be inspected to ensure compliance with City and engineering standards and the provisions of the GreenBook. The City shall not accept any paving that does not meet said standards and provisions. The following inspections are required:
  • Base Grade - One inspection - at sub-grade completion (prior to placement of base)
  • Paving Inspections - 2 inspections - prior to paving (at base grade completion) and during placement of AC
  • Driveways - All onsite private residential driveways shall comply with the approved plans and City standards, and shall be inspected and cleared by the City Engineer prior to paving
