If these structural problems are found, the old asphalt will need to be removed to dig out the soft spot of the subgrade and refill it with 2-inches of rock and aggregate. Bad soil is removed and replaced with about 12 inches of 2-inch rock and about 2 inches of dense graded stone. During the preparation phase, leveling and contouring is very ...
MnDOT is a subcontractor to Auburn (NCAT) The Minnesota Department of Transportation's Road Research facility, MnROAD, has partnered with the National Center for Asphalt Technologies (NCAT) to advance pavement engineering focusing on two important national issues that impact each agency.
All asphalt pavements will be designed based on the following design life: Interstate 20 years Bridge approaches (100 feet from bridge end) 20 years Urban projects 20 years Temporary connections/detours projected life, not less than 1 year All other locations 10 years
In 1990, at the age of 16 years, the asphalt pavement underwent a 1" hot in-place recycling treatment to correct significant thermal cracking. In 2002, at the age of 28 years, the asphalt section was milled and received a 3" overlay, consisting of a 1.5" lift of dense graded leveling mix and a …

The data obtained from MnDOT was used to create the aforementioned database. The ... to investigate if any mix design parameters (such as, asphalt film thickness, voids in mineral aggregate, asphalt binder grade) had a statistically significant effect on the field cracking performance. It also investigated the suitability of the indirect
Description Back in 2004 the Asphalt Institute (AI) and PRI Asphalt Technologies collaborated to develop a binder specification database by State. From that initiative, the AI Regional Engineers have over the years enhanced and maintained the currency of this binder spec database. Available below (as downloadable pdf files) are individual documents for each of the …
MnPAVE-ME is used for designing new concrete pavements on grade. BCOA-ME is the product of a multi-state pooled fund project to develop a mechanistic based concrete overlay of asphalt pavement design. Both pavement designs are results of MnDOT's research efforts and based on …
Minnesota DOT has different requirements based on the asphalt grade and lift type. A PG 58X-34 (where X represents the traffic level in accordance with the AASHTO M221, MSCR standard) requires a higher ratio of added new asphalt binder to total asphalt binder, since this grade is commonly specified to be used in new construction.
used to "bump" up to a stiffer asphalt to minimize rutting and shoving potential on high ESAL and high volume roads with slow moving traffic. The asphalt binder grades now used with MSCR are PG 58x -28 and PG 58x - 34. With MSCR grading the bumping is done through the selection of a letter after the high temperature grade (the 58x).
Asphalt binder grades used in the study included PG 64-22, PG 64-28, PG 70-22, PG 76-22 and PG 88-22. The PG 64-28 is a polyphosphoric acid (PPA) modified binder predominantly used in intermediate courses in the state of Ohio. The PG 64-22 was an unmodified base asphalt whereas the remaining binders were polymer modified. The PG 70-22 and PG 76 ...
Hot Mix Asphalt (HMA) Hot Mix Asphalt is defined as a specifically designed mixture of well graded aggregate combined with an asphalt cement binder. The HMA is compacted to a required density to provide for structural stability in road building. Common terms often used for …
Porous asphalt (Hansen 2008) and permeable interlocking pavements use flexible pavement design methods adopted from the 1993 AASHTO Guide for Design of Pavement Structures (AASHTO 1993). In addition, MnDOT design methods, approved mechanistic principles, and manufacturer's specific recommendations should be consulted.
Minnesota Asphalt Pavement Association. MAPA members are committed to the state and its overall quality of life. The industry is comprised of companies ranging from small driveway – paving operations to diverse larger construction companies that produce and/or place asphalt pavement on roads, airports, parking lots, recreational facilities, etc.
Asphalt Binder Grade Designation The PG Binder Grade letters should be used in all bituminous mixture designations, regardless of the specification number. These letters and PG Grade are listed below: Standard Grades Specialty Grades B = PG 58-28 A = PG 52-34 C = PG 58-34 H = PG 70-28 E = PG 64-28 F = PG 64-34 L = PG 64-22

asphalt emulsion. For MnDOT and Spokane County, this is the only emulsion used. Caltrans and TxDOT specify a wide variety of emulsions and asphalt binders in addition to CRS-2P. Some of the emulsions specified by Caltrans include polymer-modified anionic and cationic grades PMRS -2, PMRS-2h, PMCRS-2, and PMCRS-2h.
This paper's purpose is to provide an update on the pavement condition of MnROAD's three low volume road (LVR) SuperPave test cells constructed in 1999 with different asphalt binders. These cells were built to field validate the current low temperature performance grading (PG) system currently being used at MnDOT and many other agencies around ...

Only two performance-grade asphalt binder grades are used as the base binder for asphalt rubber binder (ARB). Typically, the ARB base binder chosen for a project will be an asphalt grade less than what is specified for a Caltrans pavement climate region because of the additional binder stiffness provided by the crumb rubber modifier.
