Crack sealing your asphalt will help prevent water from penetrating into your sub-base which is a major cause of pavement failure. By using state-of-the-art equipment to install hot applied joint sealants (meeting or exceeding FAA, ASTM and MHD standards) New England Sealcoating seals these cracks shut.
hot-mix asphalt – longitudinal joint sealant. Effective: March 2, 2016. Add the following to Article 406.02 of the Standard Specifications. “ (d) Longitudinal Joint Sealant (LJS) (Note 2.) Note 2. The bituminous material used for the LJS shall be according to the following table. JOINT SEALANT FOR HMA PAVEMENT 407.01 Description. This Section shall cover the sealing of longitudinal joints in hot mix asphalt pavements by the spraying or rolling of joint sealant on the vertical face of the joint ahead of the asphalt spreader. Joint sealant application shall be a separate construction operation from the tack coat application OVERLAYS USING HOT APPLIED SEALANT EI 05-015 Rev.

PCC Joint Sealant/HMA Crack Sealer Data Usage Guide Review of Evaluations and Significance of Data Generated The referenced standards provide details regarding the testing cycles and standard testing that is used for evaluation of these sealant systems. The following discussion and suggested parameters for acceptance of products is • Joint movement capability of a sealant is determined by the percentage of movement between the substrates to be sealed. Narrower joints provide less movement than wider joints. • Good architectural practice calls for joint design of four times the anticipated movement due to construction tolerances and material variations. May 07, 2020 · It’s ready in under 30 minutes to accept the HMA, so in most cases the paver follows soon after the J-Band is sprayed.” An example of specifications when a longitudinal joint sealant (LJS

Longitudinal joint performance from the bottom up. J-Band sets the standard as a Void Reducing Asphalt Membrane (VRAM) or Longitudinal Joint Sealant (LJS). But unlike other treatments, it significantly reduces air voids in longitudinal joints from the bottom up – literally.
