Trackout mat

A trackout mat comprising:

• a plurality of blocks arranged in columns and rows and configured to flex to remove debris from vehicles traveling over the trackout mat, the blocks of the plurality of blocks comprising a body having a first end and a second end opposite to the first end, a first projection extending away from and positioned between first and second upper surfaces of the body such that a first thickness between an end of the projection and a lower surface of the body is greater than a second thickness between the first and second upper surfaces of the body and the lower surface of the body at the first end of the body and at the second end of the body, a first through-hole extending through the first end of the body in a direction transverse to a length direction of the body, a second projection extending away from said first upper surface of said body and a third projection extending away from said second upper surface of said body, wherein said first, second and third projections extend from and are spaced apart by said first and second upper surfaces, and a second through-hole extending through the second end of the body in the direction transverse to the length direction of the body;
• wherein said first, second and third projections each comprise upper surfaces positioned over said first and second upper surfaces, wherein one or more of the plurality of blocks are more flexible compared to other blocks of the plurality of blocks under a predetermined load, and
• a plurality of couplings extending through the blocks of the plurality of blocks, wherein the one or more of the plurality of couplings are removable or adjustable to facilitate modifying one or more of a length, width or shape of the trackout mat, wherein
• the blocks included in an i+1th column are aligned such that the first through-holes and the second through-holes of each block in the i+1th column are aligned in an i+1th column direction,
• the blocks included in an i+1th column are aligned such that the first through-holes and the second through-holes of each block in the i+1th column are aligned in an i+1th column direction,
• the blocks included in the ith column and the blocks included in the i+1th column are alternately arranged such that the second through-holes of the blocks included in the ith column are axially aligned with the first through-holes of the blocks of the plurality of blocks included in the i+1th column,
• the alternating arrangement of blocks in adjacent columns yields space between blocks in one of said columns
• the couplings of the plurality of couplings extend through the axially aligned first through-holes and second through-holes of the blocks in adjacent columns, and
• the couplings of the plurality of couplings that extend through the axially aligned first through-holes and second through-holes of the blocks facilitate folding of the columns of blocks on top of one another with at least the projection of the blocks in one column being at least partially accommodated in the space between the rows of the blocks in a different column.
