Abstract—Formulations were suggested for highly ﬁ lled polymeric composite materials based on an acrylic
binder, with optimum combination of the high rate of strength gain (attainment of minimum required operation
characteristics) with high physicomechanical properties in a wide temperature interval of curing. A technology
was developed for using these composites under various conditions for emergency repair of cement concrete and
asphalt concrete road pavement.
Highly ﬁ lled polymeric composite materials (PCMs)
based on methyl methacrylate (MMA) are widely used for
repair and restoration works . These are cold-curable
systems allowing attainment of high physicomechanical
properties and of resistance to long action of static
and dynamic loads (including short impact loads), to
chemicals, and to frost [2, 3].
One of important advantages of acrylic composites is
considerably higher rate of strength gain at low positive
and negative temperatures , with attainment of high
operation characteristics (compression and ﬂ exural tensile
strength, adhesion to the support being repaired) in short
time , compared to analogous materials based on other
types of inorganic and organic binders [6–13]. This is due
to low activation energy of the radical polymerization
of the acrylic binder monomer in the presence of binary
redox initiating systems such as, e.g., benzoyl peroxide
(BP)–N,N-dimethylaniline (DMA) .
In many cases, the use of MMA-based PCMs is the
only possible way of repair owing to the combination of
the above advantages .
This study was aimed at developing polymeric
composite materials based on methyl methacrylate,
combining high rate of strength gain in the temperature
interval from –25 to 30°C with high strength, adhesion,
and friction characteristics and ensuring attainment of
the minimum level of strength required for the operation
within 1 h, irrespective of the curing temperature.
The following commercially produced substances
were used for preparing highly ﬁ
lled PCMs based on
MMA: crushed granite [GOST (State Standard) 8267–93]
as aggregates, molding sand (GOST 2138–91) as ﬁ ller,
methyl methacrylate (GOST 20370–74) as binder, and the
binary initiating system consisting of benzoyl peroxide
(GOST 14888–78) and N,N-dimethylaniline (GOST
The binder content of the composite was 9–15 wt %,
and the aggregate to ﬁ ller ratio was (50–70) : (30–50).
The content of initiating system components (wt %)
was varied in the following ranges: BP 1–12 and DMA
0.5–8. Curing of the composites was performed at 25, 4,
and –25°C, which corresponds to the seasonal average
temperatures in different climatic regions of Russia.
The compression, ﬂ exural tensile, and cleavage tensile
strength values were determined in accordance with
