Section 39, "Hot Mix Asphalt" and Associated SSPs
Released August 1, 2007 by Terrie Bressette, Supervising Transportation Engineer,
Chief of the Office of Flexible Pavement Materials
To be implemented on ALL projects going to PS&E on or after November 1, 2007.
On July 31, 2007 Caltrans Office Engineers (DES-OE) posted the revised Section 39, "Hot Mix Asphalt," of the Standard Specifications and 12 associated Standard Special Provisions (SSPs). They may be used in projects going to PS&E starting immediately, and, must be used in projects going to PS&E after November 1, 2007.
The revised Section 39 is included in SSP S1-020, "Amendments to the May 2006 Standard Specifications."
The associated SSP's are as follows:
- 39-AAA, "Hot Mix Asphalt" – Used for Type A and Type B HMA.
- 39-BBB, "Open Graded Friction Course" – Used for open graded overlays functioning as a friction course. Do not use for rubberized HMA open graded friction courses (RHMA-O, RHMA-O-HB).
- 39-CCC, "Rubberized Hot Mix Asphalt – Gap Graded" – Used for gap-graded rubberized HMA (RHMA-G), which is an alternative to Type A and Type B.
- 39-DDD, "Rubberized Hot Mix Asphalt – Open Graded or Open Graded High Binder" – Used for rubberized HMA open graded friction courses (HMA-O and HMA-O-HB).
- 39-EEE, "Hot Mix Asphalt (Miscellaneous Areas)" – Use for miscellaneous areas. Pay for placement and materials with separate items.
- 39-FFF, "Minor Hot Mix Asphalt" – Plans must identify HMA under this SSP as minor HMA.
- 39-GGG, "Shoulder Rumble Strip (Asphalt Concrete, Ground-In Indentations)" – Only used on existing surfacing (hence, the term "asphalt concrete"). Standard Specifications now cover rumble strips that are place in new HMA during construction.
- 39-HHH, "Hot Mix Asphalt Aggregate Lime Treatment – Slurry Method" – Used in all QC / QA construction, and when the DME recommends it on other construction methods (i.e., standard and method jobs; but use is determined by the "Interim Guidelines").
- 39-III, "Hot Mix Asphalt Aggregate Lime Treatment – Dry Lime Method" – Used in all QC / QA construction and when the DME recommends it on other construction methods (i.e., standard and method jobs; but use is determined by the "Interim Guidelines") .
- 39-JJJ, "Liquid Antistrip Treatment" – Used in all QC / QA construction and when the DME recommends it on other construction methods (i.e., standard and method jobs; but use is determined by the "Interim Guidelines") .
- 39-KKK, "Prime Coat" – Use when specifying prime coat. As its use is fairly rare, prime coat is not covered in amended Section 39.
- 39-LLL, "Replace Asphalt Concrete Surfacing" – Used for digouts.
